Claims priority, application Italy March 16, 1954 V I 4 Claims. (c1. 40-112 This invention relates to a calendar, and particularly to adesk calendar, actuated by only one control knob.

Many types of calendars are already known. Such calendars usually consist of rollers, disks, annular bands or the like, whereon the days of the month, the days of the week and the months of the year are marked in their proper sequence. I

The single components of such series are combined with respective control devices, as knobs or thelike, part of which must be actuated by the user each day, in order to have the various indications correctly up-to-dated one another.

As it will be readily appreciated, the actual usefulness of a calendar is greatly restricted by such annoying operations." e

The above'stated, and further drawbacks are positively obviated by this invention, which allows to obtain a calendar of the aforespecified type wherein all elements are actuated by only one control knob, being thereby possible to have same calendar actuated automatically, e. g. by a clock.

The calendar according to the inventive idea is characterized in that it comprises at least'three components, whereon the days of the month, the days of the week and the months of the year are marked in their correct sequences, being same components connected one another by trains of gears. One of such trains of'gears is directly actuated by a control knob which, when turned, causes the elements whereon the week days and month days are'marked, to be advanced by one step, being disengaging devices--which allows to obtain the required concordance of month days in respect of week days interposed in the connection between said elements.

In an advantageous embodiment form of calendar according to the invention, the month days are marked on one face of an annular member, while the week days are marked on a disk, secured to a pinion which can be engaged with the teeth out on the outer periphery of aforesaid annular member. Further components of the device are: a support for said pinion; spring means to move said support, in order to disengage same pinion from the annular member teeth, a second pinion secured to a disk, whereon the month days are marked; an auxiliary tooth added to normal teeth of annular member and designed' to advance latter pinion step-by-step after each complete revolution of said annular member, and a control knob, connected to said annular member in such a manner that, when actuated, both the first stated pinion and the annular member are advanced by a step, while the second pinion will be advanced by a step after each complete revolution of the annular member.

The invention will be hereinafter disclosed in the following description of an advantageous embodiment form invention, combined with writing means, to note down memoranda or'the like.

In same drawings: I v p Fig. 1 is a perspective view of the calendar according to the invention.

Fig. 2 is-a cross-section thereof.

Fig. 3 is a longitudinal section.

Fig. 4 is a plane of calendar with cover removed, and

Fig. 5 is a detail of Fig. 4.

Referring now to aforestated figures, the calendar as shown consists of a base 10, which in the present case is box-like shaped, and shows a front side 12 open and conveniently shaped, to allow the upper sheet of a pile, fitted in the box-like base 10, to be withdrawn therefrom, after having recorded notes or memoranda thereon.

The calendar is fitted within a container 14, which on its turn is fitted in the base 10. In the case in question (box-like base 10) the connection betwen same base and the container 14 is set by means of hinges 15, which allow a relative motion of base in respect of container in order to ensure an easy access 'to either of said components.

A plate 16 is fitted in the inside of container 14, and is secured thereto by means of the screws 18, being the upper face of said plate very near to inside face of container. p p

A ring 22 is rotatably fitted in a circular abutment 20 with which the upper face of plate 16 is provided. The first thirty one natural numbers (i.- e. the max. number of days in a month) are marked in sequence on the fore face of said ring 22. r

The teeth or tooth gears 24 and 26 are cut on both inner and outer peripherical edges of ring 22. The

names of the week daysi. e. Monday, Tuesday, etc.-

are stamped on the upper face of a disk 30, secured to a pinion 28, which is engaged with the teeth 26. The transmission ratio of teeth 26 to pinion 28 is set insuch a manner that, when the ring 22 is advanced by a step (i. e. is'brought from a number to thesubsequent one), the disk 30 is also advanced by a step, i. e. it is brought from a day to the subsequent one. Thus, when the teeth 26 are sixty two, as shown by way of example in the accompanying drawing, a pinion with fourteen teeth must be used, whereby the indications of ring22 can be syn-. chronized with those of disk 30. i

To the purpose which will be hereinafter stated, the pinion 28, together with its disk 30, is supported by a journal 32 fitted on the slide 34, running on the guides 36, radially formed on the circular stop 20. A knob 35, fitted on one end of said slide 34, projects out of casing 14.

The slide 34 is acted upon by the blade spring 38, which tends to keep the pinion 28 continuously engaged with the crown gear 26. By depressing the knob 35, against the action of the spring 38, the pinion 28 is brought out of mesh from the crown gear 26, whereby the ring 22 can be moved independently from the disk 30. All this in order to have-above all at the beginning of each month-the numeration of day months synchronized with the indication of week days.

The names of year months are stamped on the face of However and as already stated, a longer auxiliary tooth v 44 is added and suitably fitted to saidcrown gear, in

order that it is allowed to engage the teeth of pinion 42,

thus causing a corresponding angular motion of disk 40.. j

The pinion 42 is keyed onto a journal46, provided on one end with a knob 48, that serves for the quick driving, of disk 40. The projections 54 and 56, formed on suitable positions of inside face of casing 14, are re spectively engaged with the notches 50 and 52, cut on Patented June 24, was

the faces of the disk 40 and 30. The notches 52 of disk are longer than the notches 50, in order to allow same disk to be moved when the knob is actuated.

The notches -52 and the projections 54S6 engaged therewith have been provided in order to set the exact angular positions of said disks 30 and 40 depending on theyCOfltIOlS' performed thereto. To such a purpose, said disks are provided with spring means (as f. i. the little springs threaded on the journals 34--36) to resiliently force the disks against the projections 54-56.

The pinion 58, that meshes with the crown gear 20v cut on the outside edge of disk 22, is secured to one end of a control knob, 60, which opposite end comes out of casing 14, and is easily accessible, in order to allow the ring 22 and the disks 30 and 40 to be synchronously moved by only one control action.

The numbers and signs stamped on the faces of ring 22 and of disks30 and- 40, can be read from the outside of casing 14 through the window 62. (pertinent, to ring 22), 6 (disk 30) and (disk 40).

As shown by Fig. 1, said windows are symmetrically arranged on the vertexes of an isosceles triangle, whereby the last two of; same windows are located on the same line.

As it is tobe understood, by acting on the knob the'ring 22 is turned, whereby a given angular motion of disks 30. and 40 takes place. However, the disk 40 is advanced by a step of a turn) only after each whole revolution of ring 22.

Since in the'aforedescribed and illustrated embodiment form, the ring 22' and the disks 30 and 40 can be actuated: bymeansof" only one control knob, said embodiment form, may be advantageously combined with clockwork mechanisms, i. e. to have clocks or the like with built-in calendars according to the inventions.

Further auxiliary devices, as f..i. signal devices or the like, could also be embodied in the previously described and. illustrated embodiment form of calendar according to the invention.

In the case as, illustrated, the bevel gear68, keyed on the. journal 32 of pinion 28, drives--through the pinion 70,. a first pair of gears 72 and a second pair of gears 74.a drum 76 fitted in the inside of casing 14 and readily accessible from the outside through a window 78. Thus, when the knob 60 is actuated, the drum 66 i control knob 60 could be fitted on the journal 32 of pinion 28.

It is to be understood that the invention is not limited to the exact details of construction shown and described, as variations and modifications and changes may be made therein as fall within the scope of the claims hereunto.
